Microelectronic solid-state relay has sub-ohm on-resistance

18 May 2005 Switches, Relays & Keypads

International Rectifier has introduced the PVY117 Series microelectronic relay (MER). These devices are designed to increase product reliability by replacing electromechanical and reed relays that have fragile moving parts and metallic contacts with more reliable, solid-state relays that have no moving parts. In addition, MERs have lower power consumption than electromechanical relays since they have lower actuation current requirements, and the PVY117 Series MERs are much smaller compared to the electromechanical relays they are designed to replace.

Featuring bounce-free operation, the MER's low on-state contact resistance and low off-state capacitance maximises performance in low voltage and high test frequency semiconductor automated test equipment (ATE) and other instrumentation circuits. Other applications include low voltage audio and RF switching.

Housed in a subminiature, surface-mountable package for high-density applications, the PVY117 has a 0,95 Ω on-state resistance, 14,5 pF max off-state capacitance, and features 200/100 μs max. Ton/Toff times.
